Method of preparing Li1+xMN2-xO4 for use as secondary battery electrode

摘要

A continuous method of preparing a single phase lithiated manganese oxide intercalation compound of the formula Li1+xMn2-xO4 comprising the steps of: mixing intimately a lithium hydroxide or a lithium salt and a manganese oxide or a manganese salt; feeding the intimately mixed salts to a reactor; continuously agitating the mixed salts in the reactor; heating the agitated mixed salts in the reactor at a temperature of from about 650 DEG C. to about 800 DEG C. for a time not in excess of about 4 hours in an oxygen-containing atmosphere; and cooling the reacted product to less than about 200 DEG C. in an oxygen-containing atmosphere for a time not in excess of about 2 hours.
